20、 Pumps for Chemical Industry Use, B73,undertook the development of centrifugal pump standards to meet the needs of the chemicalindustry. Although the Standards Committee had not completed its assignment, the work of oneof its task forces resulted in the development of a de facto standard that was pu
21、blished by theManufacturing Chemists Association in 1962 as an American Voluntary Standard (AVS). Morethan a dozen manufacturers of chemical process pumps marketed pumps conforming withthe AVS.In 1965, the Hydraulic Institute published a tentative standard similar in content to the AVS,but updated c
22、ertain portions. Although the Hydraulic Institute Tentative Standard reflected morenearly the current practice of manufacturers and users, it was believed necessary to publish anew document that would supersede both the original AVS and the tentative standard, and thatcould incorporate the technical
23、 content of both documents and dimensional criteria and featuresgenerally accepted by manufacturers and users. The January 1968 revision of the AVS was thereforeapproved as an American National Standard under the existing standards method and publishedas ANSI B123.1-1971.ANSI B73.1 superseded ANSI B
24、123.1-1971 and was first published in 1974. The 1974 editionbrought to 15 the number of pump sizes covered by the standard. The committee continued tobe active, adding 5 more sizes for a total of 20, and making a number of revisions in the text ofthe standard.Shortly thereafter, the American Nationa
25、l Standards Committee B73 undertook to revise thestandard, and, as a result, new information on baseplate rigidity, bearing frame adapter, andbearing housing drain was introduced. The 1984 edition included, for the first time, informationthat covered documentation of the pump and driver outline draw
26、ing of the centrifugal pump,data sheet, mechanical seal drawing, packing box piping plans, and cooling/heating piping plans.The 1991 revision included larger and self-venting tapered seal chambers, as well as conventionalpacking boxes; revised baseplate dimensions, with a new identification numberin
27、g system; anda ductile material requirement for the bearing frame adapter if it clamps the rear cover plate tothe casing.With the expanding utilization of the ASME B73.1 pumps in the chemical process industryand its growing acceptance in the hydrocarbons processing industry, the B73 committee contin
28、uedto improve the B73.1 standard. The 2001 revision of the standard incorporated 7 new sizes ofpumps, bringing the total number to 27. Many of the new additions were at the request of theuser population. Inclusion of ISO standard size pumps was considered by the committee. It wasconsensus that the I
29、SO inclusion would have made the B73.1 standard overly complex andweakened its mechanical fortitude. Thus, this action was rejected by the committee. The “Materialsof Construction” section of the standard was expanded to include readily available corrosion-resistant alloys. Recent publications by th
30、e Hydraulic Institute in areas such as baseplate tolerance,acceptable nozzle loads, preferred operating region, and NPSH margin were incorporated intothis revision. A standardized electronic data exchange file specification was established as anintegral portion of the standard. This was, in part, in
31、 response to the needs of the user communityfor compliance to U.S. government regulations covering chemical process equipment and pumps,specifically OSHA Process Safety Management, 29 CFR 1910.119. In total, these revisions to thestandard were intended to better serve process industries and expand t
32、he use of ASME B73pumps worldwide.The 2012 revision of the standard includes several changes to reduce redundancy in the B73set of standards and to better align with the Hydraulic Institute (HI) and American PetroleumInstitute (API) pump standards. Revisions have also been made to further improve th
33、e reliabilityof the B73.1 pumps. ASME standard B73.5 on solid polymer pumps has been merged into B73.1due to the many similarities of the two standards. B73.5 will be withdrawn. Reference is nowmade to API practices for mechanical seal configurations and cooling and heating plans. Avmechanical seal
34、configuration code and a material classification code have been added to B73.1.A universal cover has been added to the standard as an alternate sealing cover. Requirementsfor the bearing frame have been revised to assure more robust pumps. C-face motor adaptersare now an option. The default performa
35、nce test acceptance grade has been revised to reflect thenew HI/ISO performance test standard. More detail has been added to the required drawings,curve, and documentation that should be included with the pump. A new data sheet has beendeveloped and added to the standard. The standard endorses the e
36、lectronic data exchangestandard that was developed by the Hydraulic Institute and Fiatech Automating EquipmentInformation Exchange (AEX) project.Suggestions for improvement of this Standard are welcome. They should be sent to TheAmerican Society of Mechanical Engineers; Attn: Secretary, B73 Committe
